How to Choose the Right Pressure Washer Nozzle?

Selecting the right pressure washer nozzle for a job is very important, but how do you know you’re using the right nozzle?

Hint: Even the best pressure washers will be more effective (and less destructive) if the right nozzle is used.

One thing to consider when selecting a nozzle is to know its intended purpose. If you’re unsure if the nozzle you’ve chosen will clean the surface without damaging it, test it out first on a tough surface.

Start by testing the pressure and water stream on a smaller surface area that you know you cannot damage. If anything, it’s always safer to start with a wider angle nozzle and work to a more concentrated or smaller angle nozzle.

Also, when you first begin pressure washing, don’t get too close to the surface.

Here are 6 of the more common nozzles!

Zero-Degree Nozzle

The zero-degree nozzle is a red colored, smaller nozzle tip used for acute blasting. This nozzle is used for dealing with tougher, hard to remove rust, tar, caked mud, and other stains from firmer materials like concrete and metal. To eliminate any stains or blemishes on surfaces, the zero-degree pressure washer nozzle concentrates the water into an intense water stream. This nozzle should not be used for softer surfaces as it will damage the weaker material.

15-Degree Nozzle

The 15-degree nozzle is a smaller sized, yellow colored pressure washer nozzle tip. This nozzle is used for stripping surfaces by removing layers of dirt, grease, mildew, marine growth, rust, paint, or other undesired layers. The 15-degree nozzle creates a slightly wider spread of water upon contact with a surface that allows it to remove a larger spread of surface stains.

25-Degree Nozzle

The 25-degree nozzle is a smaller sized, green colored pressure washer tip. This nozzle produces a larger fan of water upon contact with the surface that is great for general cleaning. With a wider water spread, the water pressure is lessened and can be used on surfaces like gutters, roofs, pools, and painted surfaces. The purpose of the 25-degree nozzle is to remove looser debris like leaves, dirt, mud, moss, and more.

40-Degree Nozzle

The 40-degree or low-pressure nozzle is a white colored tip that offers a more gentle spray option. This nozzle has a much wider water spread than the smaller degreed nozzles meaning that the water pressure is weaker and works well for larger jobs on weaker surfaces. So, this pressure washer nozzle is used for washing more delicate surfaces like windows, cars, boats, roofs, blinds, and patios.

Turbo or Rotary Nozzle

The turbo or rotary nozzle is one of the more useful pressure washer tips because it offers such an intense and effective stream. This nozzle is a rotating combination of the zero-degree and 25-degree nozzles. The turbo nozzle is so effective because of the centrifuge-like motions it produces which creates a pulsing water stream that has a strong surface impact and varied spray pattern. Rotary nozzles work well in removing rust, cleaning metal and tougher plastic, paint removal, spray-paint removal, cleaning concrete, and tougher stains removal.

Soap or Chemical Injector Nozzle

The soap or chemical injector nozzle is a very useful pressure washer tip. This nozzle is designed to combine cleaning solution with the water by decreasing the water pressure enough for the two to mix. Because of the decreased pressure that permits chemical flow out of the tip, the water pressure on the surface is also decreased. This reduced pressure allows the chemical solution and water to be applied to surfaces like cars, windows, and siding to remove grease and grime.

Each of these pressure washer nozzle options works great for various jobs and surfaces.   Once you know what you’re using the nozzle for, you’ll know which nozzle you need.

If you see a nozzle on the list that your machine didn't come with, most local hardware stores stock a variety of tips that you can just add to your unit - they are fairly universal.  But in most cases the higher quality gas and electric machines come with enough nozzles for most jobs.

Keep it simple, and spray straight!
